It is worth noting that a lawn mower is a universal and one of the most comfortable cars, which is used for gardening purposes. Thanks to the use of a lawn mower, you can create an unusual landscape design. A lawn mower can be called a highly specialized unit, since it can only be used. However, it is the lawnmower that becomes the most best assistant summer residents, owners of suburban areas. Lawn mowers are required for municipal services. With their help, parks and squares are always maintained in proper condition.

When purchasing a lawn mower, special interest and attention are always shown to it. Remember not to overload the lawn mower. The machine needs maintenance and cleaning by hand. However, over time, the lawn mower still becomes a common tool for work, which receives little attention.

Today you can find two types of lawn mowers on sale. These are electric lawn mowers and gasoline ones. If you need to mow the grass far from home, it is best to use gasoline equipment. The advantage is that a gasoline lawn mower does not rely on electricity. Doesn't affect the engine at all long-term operation lawnmowers.

The speed of cutting grass with a gasoline lawn mower is much higher than that of an electric lawn mower.
Before you launch gasoline lawn mower, you need to make sure that there is fuel in the tank, and most importantly, engine oil. If there is no oil, the engine will seize. In this case, you will have to spend a lot of money on repairs.

Electric lawn mowers are considered more economical and quieter. However, there is a clear drawback to electric lawn mowers - their lack of mobility. And it is limited by the length of the power cord. You need to be close to an outlet at all times. Moreover, during operation the wire often gets tangled and has to be corrected.

Before turning on the electric lawn mower, you need to check whether the power cord and the outlet itself into which it is plugged are intact. Under no circumstances should an electric lawnmower be used during rain or dew. This technique can only be used on dry grass.

The operating rules for gasoline and electric lawn mowers are approximately the same. You should always follow the rules that are clearly stated in the instructions from the manufacturer. It is important to pay attention to the moment when you need to take a break from operating the device. For example, if the engine of a gasoline lawn mower overheats, this will lead to its failure.

After each work process, you need to remove any remaining grass from the knife and other parts of the equipment. The lawnmower should be stored in a dry place where it will not be exposed to danger. precipitation. As soon as work is completed, it must be turned off so that there is no threat to the health and life of your loved ones. When the device is running, you cannot inspect the equipment. If you find any problems, you need to contact service center where you will receive qualified assistance. A problem that is identified in time will allow you to avoid costly repairs in the future.

If there is very large and thick grass growing on your site, then you cannot mow it at one time. You need to go over the lawnmower several times. The grass should be removed gradually so that the lawnmower is not overloaded.

To ensure that the knife does not become dull when it hits the ground, you need to avoid uneven areas in the area. In order for the lawn to be cut beautifully and correctly, you need to carry the device only forward. To prevent the lawn mower from harming you, you must wear protective clothing and shoes. The lawnmower should not be used where there are stones, curbs, or debris. All this can lead to damage to a running lawn mower.

Now is the time to talk about how to properly use a lawn mower, as well as how to properly repair and service it.

First of all, we’ll tell you how to sharpen blades on lawn mowers. Let's say right away that on gasoline and electrical devices the principle is the same. First you need to turn off the power to the lawnmower. Then we put the device on the brake. The protective cover is removed. After the lawnmower is turned on its side, you must put on latex gloves or others, so as not to get hurt. Use a brush to clean visible parts from dirt and grass. Then we remove the knife and fix it in a vice. Now you can start sharpening the knife using a file. If the knife is bent during operation, then it is necessary to straighten it. To do this, place the product on a flat surface and level it with a hammer.

Watch a useful video about sharpening lawn mower blades

Once all the work is completed, you can put it in place. Most often, knives begin to be sharpened in the spring, when the first mowing occurs. During the season, the knife does not need to be sharpened.

According to him, everything is so simple, but when a person who does not understand anything about this matter takes on the job, many difficulties immediately appear. It's best not to do the work yourself. Entrust it to the specialists. Improper sharpening will result in the knife being thrown away. To remove the blade from the lawn mower, you must use a socket or spanner wrench. There is no need to re-tighten the bolt too much, as you will have to unscrew it again later. Moreover, the force will cause the thread to be torn off.

How to care for your lawn mower

Must be cleaned after every mowing inner part lawn mower cover. Grass that collects on the device can not only interfere with further work, but also cause a fire. Do not use chemicals to clean the lawn mower. This may damage some parts. If you wash some parts with water, then you need to wipe everything very well and dry. As soon as even a little paint leaves the metal, corrosion will immediately begin.

There are such modern models, which have a fitting available. A hose is connected through it. The water turns on and the lawnmower starts. While the knife rotates, it is washed.

All lawn mowers have engines with air cooled. To prevent the engine from overheating, you need to constantly clean its fins on the radiator. To clean the motor, sometimes you have to remove some parts. Great option Engine cleaning involves using a compressor that supplies compressed air.

For performance and performance engine is affected by the quality of the fuel. After the last use, you need to drain the gasoline from the gas tank. It's best when it's all worked out. So, you need to crank the starter so that all the valves close. So we leave the equipment until next season.

Sometimes the engine oil and spark plugs are changed on lawn mowers. The oil is changed when the manufacturer requires it. Only special oil of viscosity and class is used. There are engines where the lower compartment opens to drain the oil, and sometimes you need to turn the lawn mower on its side.

It is better to drain the oil immediately after work. Then precipitation will not have time to form in the crankcase, and the viscosity of hot oil is much lower.

If the spark plugs are rusty or burnt out, they need to be replaced. You can simply clean the spark plugs, but it is better if a new one is installed. The air and fuel filters also need to be cleaned and, in some cases, replaced.

Storing the mower

Lawn mowers should be stored indoors and dry. Moisture, snow - all this is unacceptable for equipment. Make sure that children or animals do not approach the lawnmower. Only a dry and clean lawn mower is sent for storage.

When do we have to choose gasoline lawnmower For own plot, then first we pay attention to such characteristics as maneuverability and lightness.

How choose petrol lawn mower (trimmer)?

When we have to choose a gasoline lawn mower (trimmer) for our own site, we first pay attention to its characteristics such as maneuverability and lightness. Lawnmowers today there is a great great amount, But in great demand Gasoline trimmers are used specifically due to several advantages over analogues, for example, electric mowers. They are autonomous and strong, requiring only a certain level fuel.

Features of choice

So, let's figure out how to choose a gasoline lawn mower, what should you pay attention to when buying?

The main features of this type of device:

• do not require connection to power sources;
• a short period of time to process a huge area;
• created for a plot of more than 3 acres;
• work with ease even on a site with difficult terrain;
• have the highest power;
• They can not only cut lawns, but also mow them.

All gasoline mowers can be divided into several types depending on their suitability for a particular area, more precisely, its landscape, the size and type of grass planted on it.

• Thus, household lawn mowers are ideally suited for small areas of up to eight acres, their power reaches 5 horsepower, the longest resource is about 500 engine hours

With all this, you should know that, usually, companies that produce this kind of equipment do not manufacture engines themselves, but install ready-made ones from companies such as Tecumseh, Subaru, Briggs & Stratton. The only exception is the Honda brand.

• namely, various models They also differ in the volumes and types of containers – grass catchers.
• Thus, fabric containers are very spacious, so they are suitable for processing large areas, but they are difficult to wash.
• A plastic grass catcher, on the other hand, is easy to clean or wash, but if it is installed on a mower that collects more than 50 liters, filling may be difficult.
• The most rational option for a grass catcher can be called the so-called combined type, where side surfaces made of fabric, and the bottom (or top) is made of plastic. This type is usually installed on mowers with a huge capacity, which belong to the premium class.

Now a few words about the process of lawn mowers, or more precisely, about some of their features in this regard.

Depending on how the height of the mowed grass is adjusted for each device, they can be divided into several types:

• lawn mowers with screw-type adjustment are cheaper; the indicated type of adjustment is presented in the form of several holes of different heights, where the axle with wheels is rearranged to configure the height of the bevel;

safety when working with a lawn mower

All lawn mowers also move differently, this is explained by the difference in drives. When thinking about how to choose a self-propelled gasoline lawn mower, you need to pay special attention to this nuance:

• If the device is equipped with a front drive, it will be very maneuverable, but in the process of filling the container for mowed grass, the front wheels may slip, since the center of mass in this case will be shifted back.
• Rear-wheel drive is more comfortable, here the main load falls on the rear wheels.

Another point to which you should pay attention if you are deciding whether to

The process of commissioning a lawn mower, whether you bought it now or got it later winter storage, the rules listed below will allow you to avoid basic mistakes that can damage the instrument.

Let's assume that you just bought petrol trimmer. Take the instructions out of the box and see if you have all the parts of the lawn mower that are indicated. After this you can start assembling.

Preparing the fuel mixture and refueling

For the convenience of preparing a fuel mixture, it is better to have one where one part contains gasoline and the other 2-stroke oil. We recommend getting one like this, it’s very easy to use.

Next, take a measuring container with a scale marked on it; with its help you can prepare the mixture as accurately and quickly as possible. Look in the instructions to see what brand of gasoline and 2-stroke oil are recommended by the manufacturer of your model of lawn mower. Pour gasoline and oil into the container for preparing the fuel mixture, according to the proportions specified in the instructions. Then ready mixture carefully, through a funnel, pour into fuel tank trimmer. The ratio of gasoline and oil should be exactly as indicated in the instructions. This is a very important point!

Starting a lawn mower with a cold engine

To start the lawnmower for the first time, find the choke lever and place it in the “closed” position. Turn on the ignition on the handle. If your model has manual fuel pump, popularly called suction, then press it 3-5 times until you see the primer inside fuel mixture. The tool is now ready to run. Place the trimmer on flat surface to ensure a stable position. Smoothly pull the starter cord until you feel resistance, and then with a sharp movement, pull the cord towards you 3-5 times.

If the engine starts after 5 jerks, open the choke. If this does not happen, open the choke anyway (if open damper and continuing to try to start the engine, fuel will flood the spark plug and you will have to dry it, and this is a waste of time).

If the engine does not start with the throttle open, close it and continue pulling the cord. The first launch can be quite difficult and require up to 15 jerks. After the engine starts running, press the gas lever once to engage the idle speed. Now let the engine run and warm up. After this, it can be stopped by pressing the "Stop" button.

Starting a warm engine

It's very simple. Move the switch to the operating position and pull the cord until it starts. If you do everything according to the instructions, then there should be no problem starting a working lawn mower.

Basic mistakes when starting

Let's list the main mistakes that beginners make when starting a gasoline trimmer:

• starting the engine with the ignition off;
• starting with the valve closed with more than 5 jerks;
• incorrect fuel mixture.

Active exploitation garden equipment leads to rapid failure of individual components or parts. There is no need to dispose of the equipment, as it can still be useful in the future. After all, having spent sometimes minor repairs lawn mower with your own hands, you can return it to its previous working condition.

When the lawn mower won't start

Depending on the area of ​​the lawn and the growth of the grass on it, owners choose the equipment that has the optimal characteristics. It comes in several types:

• gasoline devices;
• units with an electric motor;
• battery powered equipment.

An average-priced mower can withstand climatic conditions St. Petersburg, Moscow or similar regions for about four seasons. More expensive or less used garden helpers capable of withstanding field conditions 5-6 seasons.

Do-it-yourself restoration of lawn mowers will also be required if the winter storage conditions turned out to be inappropriate. For example, after use, work surfaces were not cleaned or there was no interseasonal preventative maintenance. This results in a variety of problems:

• frequent sharpening of lawn mower blades is required;
• The lawn mower just won't start;
• the engine starts, but after a short period the lawn mower stalls;
• malfunctions appear in the carburetor, which requires not only disassembly, but also cleaning and repair;
• Do-it-yourself lawn mower repair is required when there is a significant decrease in power during operation.

There is no need to go to an expensive service center. Many problems can be solved with minimal costs and carry out the repairs yourself.

The tool must be cleaned after each use. cutting elements. Change the oil regularly and carry out maintenance to minimize the risk of breakdowns.

Restoring the functionality of electrical equipment

Mowers that have electric motors inside most often begin to act up due to oxidation of the contacts. The terminals become covered with a layer of scale from excess humidity in the room or other storage location. It is also worth checking that there are no wire breaks in problem areas. For this operation, use a multimeter or other type of tester.

When a set of garden equipment contains a brush motor, we determine the functionality of the moving unit. Brushes can wear out quickly, resulting in a lack of contact. A repair kit with them costs relatively little, and is easy to find in specialized stores that sell spare parts for such equipment.

Malfunctions await and asynchronous motors. Phase-shifting capacitors fail in them. This situation is difficult to diagnose at home. It can be identified by indirect symptoms:

• a buzzing sound is heard;
• when starting, the body twitches slightly;
• the motor heats up significantly even under light load;
• speed decreases.

It is worth diagnosing the state of the turning on toggle switch/button and the voltage supply to the electric motor. When the described components have been tested and no malfunctions have been found, it is unlikely that you will be able to fix the breakdown of the lawn mower yourself. Then you will have to use the services of a branded service.

Main problems with gasoline cars

Primary diagnostics is carried out from the stage of eliminating the most obvious breakdowns. When the engine does not start, it is worth checking the presence of fuel in the tank. If there are any leftovers from last season, then it is worth replacing it. After wintering, low-quality gasoline can lose its characteristics, give an unwanted sediment, or even separate into fractions based on density. In this form, it is not able to start the engine, but will only clog the system.

At the second stage, we find out why the spark does not appear. Its loss will prevent the fuel from igniting. We remove the cap from the spark plug and unscrew it from the seat using the special key that came with the mower. Next, we put the cap on the candle, bring it closer to the threaded part or metal element engine, and at this time the partner pulls the starter.

With such manipulations, a powerful blue spark should appear in the working unit. It can be noticed even with daylight. It is important to test this near an unpainted metal part of the motor that can conduct current.

When there is no spark, you need to go for new candle to the store. Do not return it to the engine even if the spark is weak or unstable. It is better to first clean the working contacts on the head from carbon deposits.

During operation, rattling may occur in the structure. At first, it does not affect the performance of the mechanism as a whole. However, it can lead to imbalance and increased noise while working. It is worth tightening the fastening bolts on the frame in a timely manner.

An uneven cut in the grass is an indication that your lawn mower blade needs to be sharpened. Getting to them is not so difficult, but it is important to completely disconnect the equipment from the power supply. You can do the work yourself using yews and a file or using sharpening sandpaper. It is important to ensure a uniform cutting angle along the entire line of 30 degrees. If there are chipped areas in the surface, this is evidence of exposure to hard surface. Replacing them will be quite expensive.

After switching on, a whistling sound appears. An unpleasant acoustic effect is associated with the penetration of foreign elements into the structure. They can block the roller in the aerator. You can solve the problem by turning off the blocked roller and then removing the foreign object.

The engine of gasoline equipment becomes almost immediately after starting short work. The culprits are a seized crankshaft or piston. At the same time, check the presence of oil in the crankcase. With the engine turned off, manually start the rotation or add oil as necessary. However, in such a situation you often have to turn to specialists for restoration.

Problems with the carburetor and fuel system

Before you start repairing the lawn mower engine, it is worth checking whether the pistons are stuck. To do this, it is necessary to dismantle the motor. We also remove the carburetor from the structure and carry out a visual inspection for possible defects. Typically, disassembly will require a special TOREX screwdriver with bits.

We inspect the gaskets to identify ruptures or burnouts. If this is found, then you need to ensure the tightness of the structure by replacing them with new ones. The air damper may contain a layer of carbon deposits, which reduces the quality of the air-fuel mixture. You need to get rid of it by cleaning the carburetor by washing the unit in solvent or kerosene.

Choking during operation or failure to dial them to enter operating mode, together with overheating of the power unit, are the causes of the following events:

• Violation of regulation idle move. You can use a screwdriver to unscrew the jets to the correct position yourself. You can do this even by ear so that the motor runs smoothly. The knives do not need to be removed, but they should not rotate.
• There is contamination air filter. It is enough to take it out and clean and rinse. Dry in natural conditions in the wind, without placing it near the stove or fireplace.

Remove the carburetor fuel chamber cap and clean it. An ordinary Vedashka is quite suitable for this, but you can also buy a special liquid

To clean the fuel chamber, first wipe it with WD-40, then soak it for 15-20 minutes, and wipe it again. This needs to be repeated 3-4 times to completely clean the chamber and channels.

A clogged exhaust causes a narrowing of the output flow. exhaust pipe. Resins appear on inner surface due to an incorrect ratio in the mixture of fuel and oil. We twist the crankshaft so that the piston goes up to the maximum and clean its surface with a wooden stick.

In more serious cases, it is recommended to contact the warranty service. Otherwise, unprofessionalism will cause more damage. Moreover, when independently searching for malfunctions and repairs during the period warranty period, the warranty is no longer valid.
